AUTOMATIC CHECK FOR PHONOGRAPHS.

Specification of Letters Patent.

Patented Get. 18, 1910.

Application filed July 26, 1909. Serial No. 509,475.

I To all whom it may concern:

States, residing at White Bear Lake, in the county of Ramsey and Stateof Minnesota, have invented certain new and useful Improvements inAutomatic Checks for Phonographs, of which the following is aspecification.

This invention relates to improvements in automatic mechanism forstopping the motor of a phonograph when the reproducer has reached theend of the record cylinder:

An object of my invention is to provide an extremely simple andinexpensive device of this character which may be readily attached tophonographs at present constructed and which may be adjusted to conformto graph mechanism.

prises the main longitudinal the various Another object is 4 to providea device which will be automatically set in the proper position forstopping the motor of the machine, when the starting lever has beenmoved to its proper operative position,

A further and more particular object is to provide a controlling leverand support therefor of novel and simple construction.

In the drawings; Figure 1 is a perspective view of the large size typeof phonograph, showing the stop mechanism applied thereto, Fig. 2 is asimilar view of-a smaller size type of machine, with a slightmodification of my device, Fig. 3 is a detail view-of the controllinglever, comprising my invention.

Referring to Fig. 1 of the drawings, 1 in-- dicates the casing for themotor mechanism, and 2 the frame This mechanism comshaft 3, the cylinder4, the feed block 5, the reproducer arm (3, and the reproducer 7. Thesevarious elements comprise the principal features of the ordinaryphonograph as at present constructed and are su tably connected and0perated by the motor mechanism contained within the casing. In thistype of machine the stopping lever 8 protrudes from the casing through aslot 9 formed in the base plate of the supporting frame 2, and extendsfor some distance above the top thereof. To the upper end of this leverone end of the longitudinally extending controlling lever 10 is secured,this lever being supported upon the base plate of the frame 2 by meansof links 11 which are pivotally supported upon said lengths of therecords which are upon the cylinder.

which supports the phono- I plate and connected to the controllinglever,Be it known that I, JOHN J. Monmssnv, a citizen of the United so thatlongitudinal'movement of the controlling lever will oscillate thestarting lever, and the controlling lever will rock upon the links. Theother end of the controlling lever 10 is extended rearwardly andupwardly as shown at 12 and its posit-ion with relation to thereproducer of the phonograph mechanism, is such that the same willcontact with the portion 12 of the controlling lever to stop theoperating mechanism, as will be later described. The links llare carriedby suitable bracket platesll having two perforations therein receivingsuitable fastening members engaged with a part of the phonograph frame,the plates being provided at one side with an upwardly extendedperforated ear 11 in which there is engaged a suitable pintle, uponwhich thelink is pivotally carried. The brackets 11, the links and thetwo members of the controlling lever,10 are all formed of sheet metal,which reduces the cost of the device to a minimum and simplifies itsconstruction to a marked degree) V To provide for the stopping of themechanism at various periods of the longitudinal movement of thereproducer, the arm 12 cured to the controlling lever 10 and leadjustable with relation to the end of the cylinder. A recess 13 is formedin one side of the controlling lever 10, said recess opening atthe endof the lever opposite to the of connection with the starting lever 8 andthis extension 12 has-its lower horizontal point portion suitablyreduced in width and thickness and is disposed slida-bly within therecess 13, the shoulder formed by the reducing of this horizontal,portion being adapted to abut the end of the controllinglever, when-atthe limit of its inward movement. A longitudinal slot 14 extends thegreater portion of the length of t-hehorizontal portion of the member12, the shank of the set screw 15 being extendedthrough the same, andscrew threadedly engaged in the extremity of the controlling lever, bywhich means it will be seen, that the member 12 may be extendedoutwardly longitudinally of the phonograph cylinder, so that the wardlyextended portion rearwardly and up thereof may be disposed to engage thereproducer at the point at which the record of the cylinder terminates.The set screw 15 machine.

't peo will secure the member 12 in its adjusted po- 11, which arepivotally connected with the base of the frame 2 will thus be disposedat an inclination to the controlling lever and when the starting leveris again actuated to start the operating mechanism, the controllinglever will be drawn to the left, whereupon the links 11 will vagainassume their vertical positions and the rear ardly and upwardlyextending end portion of the controlling lever will be returned to itsnormal operative position.

In Fig. 2 I have shown my improved stoppin mechanism applied to thesmaller phonograph now in common use.

11 this COIIStI'L'lCtlOIl of the machine, the main shaft 3, above whichthe feed block 5 is disposed, is located behind -nd in parallel relationto the cylinder 4. T he reproducer arm is directly connected with theshaft 3, and extends over the front of the cylinder and has securedtherein the reproducer 7', thus greatly contracting the length of theThe stopping device does not essentially differ from the constructionwhich is employed in the machine shown in Fig. 1. In this form, however,but one link 11 is necessary to support the longitudinal controllinglever 10. This link is pivoted to the lever and to the base of thesupporting frame, and operates inasimilarmanner to the links 11 aspreviously described. One end of the controlling lever 10' is secured tothe upper end of the starting lever 8, and is adapted to actuate thesame to start and stop the operating mechanism when moved to either endof the slot 9. The other 'end ofthe controlling lever is extendedrearwardly and upwardly and is adapted to be engaged by the lower end ofthe reproducer to move the starting lever to the right, when thereproducer has reached the end of the record upon the cylinder. Thecontrolling lever 10 will also returned automatically to its normaloperative position by the movement of the starting lever to the leftwhen it is desired to start the operating mechanism.

' mazes From the foregoing it will be seen that I have provided anextremely simple inexpensively'constructed device which may be readilysecured upon phonographs of the various types as at present constructed,and requires no especial provision by means of which the same is to beattached to the supporting frame. I My improved stop mechanism isparticularly adapted for use upon commercial phonographs, where-it isessential-that the operator should be relieved from the many attentionswhich it is necessary? that he should give to the machine during thetranscription of the record. .By the use of my improved stop mechanismthe operator may give his entire attention to the elucidation of thematter recorded upon the cylinder, whereby much better results may besecured than have heretofore been possible.

What is claimed is An automatic stop for phonographs or the like,comprising a combination with a frame, a lon tudinally movablereproducer and an oscil ating starting lever projecting upwardly throughthe frame, of a controllin lever secured at one end to the a per en ofthe starting lever, said controlling lever having a long tudinal recessformed in one side thereof and opening on the opposite end to thatsecured to the starting lever, a bracket plate secured on the framebelow said controlling lever, said plate having an upwardly extendingperforated ear, a intle therethrough, a link pivotally mounte upon saidpintle and pivotally connected to said controlling lever intermediate ofits length, a rearwardly and upwardly extended arm having a horizontalextension, said horizontal extension being reduced in width andthickness for a greater portion of its length, said reduced ortion beingprovided with a longitudinal s ot throughout its length, said reducedportion being slidably. mounted in .the recess, a setscrewextendingthrough said controlling lever, 'said arm being adjustably disposed in the path of therepro- JOHN vJ.
